JOHN S. BARDEN, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO ROCKVOOD.

HIMSELF AND AARON W.

HYDRAULIC METER.

Specification of Letters Patent No.

To all whom it may concern.'

Be itknown that I, JOHN S. BARDEN, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Vater-lvleter; and I do hereby declare that the same is fully described and represented in' the following specification and the accompanying drawings, of which- Figure l, exhibits a side elevation of said engine or meter. Fig. 2, is an end elevation of the same. Fig. 3, is a transverse section taken through one of its oscillating cyl inders. Fig. il, is a horizontal section of the stationary partitioned cylinder and chamber to be hereinafter described.

In these drawings, A, is a cylindrical vessel whose internal space is divided by a vertical partition a, into two semicylindrical chambers, Z), o, the partition being extended axially through the vessel, A, and terminating against the two heads, el, e, thereof. An induction pipe or passage, B, leads into the chamber, at one end of it as seen in Figs. l and 4. The chamber, o, is also provided with an eduction` o-pening or passage, C, leading out of it as seen in said Fig. 4. On the top of the vessel A, there is arranged three or any other suitable number of cylinders or pump barrels, D, E, F, they being` made to extend above the same as seen in the drawings. The lower part of the bottom, e, of each barrel, D, E, or F, is curved or formed with a seat to lit closely and move upon the top surface of the cylinder and transversely across said surface during the oscillations of the cylinder. Each of the pump barrels is held down upon the vessel, A, by means of a curved yoke, G, and a set of screw bolts H, H, H, respectively carrying springs, O, O, arranged upon them as seen in Fig. 3. Every one of said springs rests upon a shoulder or projection, f, extended from the pump barrel, the upper end of the spring being borne down or pressed upon by a screw nut g, screwed upon its bolt, H.

By means of the yoke, springs and bolts applied to the vessel, A and the pump barrel, the latter during its oscillating movements is maintained closely against the top surface of the vessel, A, and so as to preserve a water tight joint between, such being the purpose of the yoke, the springs, and draw bolts. Through the bottom of each cylinder 14,335, dated February 26, 1856.

or pump barrel, there is a hole or passage h,

and the upper surface of said bottom is made concave or dishing toward said hole or passage as seen at i, and below the lower terminus of the path of the piston of the pump barrel in order that any sediment or foreign matter which may gain access intol that part of the barrel, which is beneath the piston may have a free opportunity of being discharged through the hole, L, and without adhering to the piston or being an obstruction to the movement of the same.

Directly underneat-h each of the pump barrels, and arranged on opposite sides of the partition, a, two passages, P, Q, are made through the top part of t-he vessel, A, the same being as seen in Fig. 3. One of these passages may be considered as an induction and the other an eduction passage with reference to the pump barrel. There is a piston R, applied within and to each pump barrel, the several rods of the several pistons being exhibited at S, T, U, and as connected respectively to three bell cranks V, W, X, of a horizontal shaft Y. These cranks are arranged so that they may radiate from the axis of the shaft and each stands at an angle of 120, with respect to that which is next to it, their respective positions being as shown in Fig. 2.

The above 'constitutes my improved water meter which when in use,.is to operate in the following manner, that is to say water is to be allowed to flow through the induction pipe B, into the chamber, and under pressure. If the hole 71 of the pump barrel, D, be directly over the induction passage, P, immediately underneath said barrel, the water will flow from the chamber Z), into the barrel, D, act against its piston so as to elevate the same and cause its rod to turn the shaft, Y, and so as to force the pump barrel to move laterally in one direction with respect to the vessel, A, and until the hole, h, comes directly over the passage, Q, so that t-he water in the barrel may escape into the chamber, o. This movement of the pump barrel in consequence of its peculiar connection with each of the other barrels will create corresponding movements of them and they are so arranged, that they coperate each in its turn, being so moved as to bring its receiving orifice, L, direct-ly over the induction passage-P, immediately under it. While a barrel is moving in one direction, the next barrel will be moving in the opposite direction, the piston of one being drawn upward while that of the ot-her is being moved downward so that when any piston is being depressed the water below it in its barrel will be forced into the chamber c, while when a piston is being elevated water from the chamber, will be piping into its pump barrel and acting against such piston. By employing three pump barrels and arranging the bell cranks thereof as described, a continuous rotation of the shaft will take place, each barrel in succession receiving a like quantity of water from the chamber, b, and being made to discharge it into the chamber, c, from whence it will escape through the eduction passage, C. Knowing the diameter of each barrel 0 o 0 o as well as the extent of upward movement of its piston, we can readily estimate the amount of water it will receive and discharge during each entire revolution o-f its cranks. Therefore if to the shaft we ap ply mechanism to indicate the number of revolutions it may make we can readily measure the water which may have flowed through the engine. Were we to employ but two pump barrels, and have the cranks of their pistons arranged in one plane and eX- tending in opposite directions from their shaft it would be difficult to overcome their dead points so as to maintain a continued rotation of the shaft, but when three or a .greater number of barrels are used this dif-- ficulty ceases.

I claiml. A partitioned hollow cylinder or chamber, and two series of induction and eduction passages arranged with respect to the partition of said chamber, substantially as described in combination with three or any other suitable number of oscillating cylinders and pistons connected together and applied to the partitioned cylinder and made to operate essentially as explained and for the purpose of receiving and discharging water or any other Huid or measuring the same as set fort-h.

2. I also claim combining each oscillating JOHN S, BARDEN. Witnesses:
